I think I did it very quickly at first, other times I’ve had no success. One of the other reviews mentioned connecting it to wifi before you open the app and that definitely worked for me this time. I also made sure it’s fully charged and my phone as well. ### 3/5 — не отображается картинка с камеры *2026-04-20* пару недель все работало хорошо, но потом стало глючить картинку после пары секунд использования, с вайфаем проблем не было, но смысл в нем если картинки нет🥲 ### 1/5 — Stopped working *2026-04-07, version 1.0.5* Worked ok for a little then app stopped showing the camera footage for no reason ### 1/5 — Great when it worked. *2026-04-04, version 1.0.5* Had the same issue as others. Was clear and user friendly but on second charge of camera the Home Screen kept flicking over and no camera opened ### 1/5 — DO NOT RECOMMEND *2026-03-30, version 1.0.5* The directions are TERRIBLE. Even after following the directions on the review, the app did not allow me to connect to the network. This was a waste of money and data download! ### 1/5 — Worked fine in the beginning *2026-03-08, version 1.0.5* Worked fine early, but now it’s laggy and unusable. Installed, reinstalled, and it still doesn’t work. Junk. ### 1/5 — Bad app *2026-02-25, version 1.0.5* Not usable ### 1/5 — USELESS *2026-02-25, version 1.0.5* iPhone screen menu dies not match the instructions. No option to connect WLAN/WIFI ### 1/5 — App design sucks *2026-02-21, version 1.0.5* It keeps on asking me to go to settings and allow it to connect to local network, & won’t let me use the app until I do, I already went to settings and did this, it still asks, and I can’t do anything or use the app, I have try deleting and reinstalling, turning the setting on and off, but it doesn’t work ### 1/5 — Takes up too much storage *2026-02-09, version 1.0.5* Waaayyy too much storage ### 1/5 — Inutilisable *2026-01-31* Jamais réussi à me connecter ! ### 1/5 — App doesn’t work rubbish *2026-01-26, version 1.0.5* Rubbish ### 1/5 — Randomly stops working *2026-01-26, version 1.0.5* Besides it being a low quality rubber on some metal it works well when it connects, have had it happen multiple times where the app glitches and I can’t use the device, please update and fix ### 1/5 — Бестолковое приложение *2026-01-25* Не открывает и не читает ### 2/5 — It’s ok *2026-01-16, version 1.0.5* Works great for about 2 weeks. Then won’t connect so uninstall reinstall and good for about 2 weeks ### 1/5 — Camera doesn’t work with app *2026-01-09, version 1.0.5* I was able to connect to the device WiFi but nothing from the camera shows in the app. It says “connected” but it’s just a blank screen. Waste of time and money. Do not buy. ## Most critical reviews (10 lowest-rated) ### 1/5 — Not working *2026-08-06, version 1.0.5* I tried to pair the device to my phone to the app and nothing it keeps taking me right back to the beginning and it’s just not working ### 1/5 — Glitches all the time. *2026-06-26, version 1.0.5* It will glitched where u can can’t see or tap anything in the app and force u to a black white screen with a few controls at the bottom. it will happen 80% of the time. ### 1/5 — All around terrible *2026-06-04, version 1.0.5* App absolutely refuses to connect to its own special network, no matter how long you sit there and press to connect over and over again it says that it can’t, product doesn’t work for the one thing everyone got it for, which is the camera. ### 1/5 — Do not buy *2026-06-02, version 1.0.5* It does not work with the link ### 1/5 — Not working *2026-05-27, version 1.0.5* It doesn’t matter how many times I try to set this up for the instructions. It’s not working the first day. It worked one time and never again has it worked. It just keeps going to the Settings page. I don’t know what it wants me to do. I don’t have any instructions. It makes no sense so now I have to return this thing. Goddamnit it sucks. ### 1/5 — Trash *2026-05-19, version 1.0.5* Bad app don’t work with my product even tho it worked only 1 time 🥱 china ### 1/5 — laggy and garbage *2026-05-13, version 1.0.5* garbage product and horrible software ### 1/5 — mad *2026-05-03, version 1.0.5* didn’t know i had to pay for the app, untill it payed for its self on my card, i recommend them to tell you and not use your stuff i will not be using this i’m mad at this point ### 1/5 — No connection *2026-05-01, version 1.0.5* The device does not seek WiFi - only tracks to system for permissions and never moves beyond regardless if all, none or some of permissions granted. Never options WiFi . Blue light flashes and tip lights however no connection - software makes this a nonstarter ### 1/5 — connection *2026-04-28, version 1.0.5* app connects but only detects for 2 seconds and then freezes and you have to disconnect and reconnect for 2 more seconds. fix the app ## Most praised reviews (10 highest-rated) ### 5/5 — The *2026-05-24, version 1.0.5* The ### 5/5 — 🫶🏻 *2026-05-19, version 1.0.5* Idk why this has low ratings it’s really good in my opinion ### 5/5 — App needs to update *2026-01-27, version 1.0.5* App won’t work with the new iOS update ### 5/5 — Overall good *2026-01-08, version 1.0.5* I read the reviews first and was skeptical but I follow all the directions and it asked me if I wanted to connect and I said yes and it was good from there,i could see in my ear and got some good earwax out.It might be a little difficult to get into your other ear cause it was easy for my right ear but the left one I couldn’t get the angle right ### 5/5 — 好用 *2025-10-30* 跟可视化挖耳勺基本上没什么延迟，挺好用的 ### 5/5 — Все работает *2025-09-10* Просто нужно искать не в настройках приложения, а телефоном подключиться к wi-fi устройства , и все заработает ### 5/5 — Works Great *2025-08-30, version 1.0.4* This app works great once you figure out the setup. Grateful I peeked at some of the other reviews on here before I started. Everyone on in the reviews is right, you pair through WIFI and NOT Bluetooth. Also just wanted to mention this in case anyone is like me — having a VPN completely screws with this if you have one. Mine wouldn’t pair to the app and couldn’t figure out why because I forgot about my VPN. Paired right away once I turned it off though. So far, everything else in the app works perfectly! ### 5/5 — Bad investment. App in Chinese *2025-08-22, version 1.0.4* Can’t figure how to work this thing. App is in Chinese and no way to get support. Now I need to figure out how to get my money back ### 5/5 — Всё работает *2025-08-14* Интересная штуковина. Приложение нормальное. Подключилось без проблем. Всё работает. ### 5/5 — No lag great application *2025-07-28, version 1.0.4* Unlike the other applications, this one has no lag and works extremely well with my product! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
